Embodiment 1

[0220]

[0221] A composite aspheric lens was manufactured by the manufacturing process shown in FIG. 11 .

[0222] As shown in FIG. 11( a ), a spherical lens made of glass is used as the optical base 1 , and after the intermediate layer 2 is formed on the optical base 1 , the solution 3 for forming an optical resin layer is dropped thereon. As the optical substrate 1, a high-refractive-index glass spherical lens (refractive index nD of glass = about 1.8) having a diameter of 5 mm and a maximum thickness of 1 mm was used. The intermediate layer 2 was formed by spin-coating a silicon oxide particle dispersion and heating at 100° C. for 1 hour.

[0223] As shown in FIG. 11( b ), the mold 10 made of nickel with an aspheric surface shape on the inner surface is pressed on the solution 3 for forming an optical resin layer, and then, as shown in FIG. 11( c ), irradiates The ultraviolet rays cure the optical resin layer forming solution 3 to form the optical resin layer 3 . Speci...

Embodiment 2

[0229] As shown in FIG. 2 , the intermediate layer 2 is formed by the coupling agent layer 6 provided on the optical substrate 1 and the matrix resin layer 4 in which the silicon oxide particles 5 are dispersed. In the same manner as in Example 1, a composite aspheric lens was produced.

[0230] The coupling agent layer 6 was formed by spin-coating the coupling agent solution 3 and heating at 140° C. for 1 hour. The thickness of the coupling agent layer 6 is 10 nm. The matrix resin layer 4 was formed in the same manner as in Example 1. Its maximum thickness is 200 nm.

[0231] Therefore, the thickness of the intermediate layer 2 in this embodiment is 210 nm.

Embodiment 3

[0233] In this embodiment, niobium oxide particles are used as the fine particles 5 . A composite aspherical lens was produced in the same manner as in Example 2 above except that the niobium oxide particle dispersion liquid was used for forming the matrix resin layer 4 to thereby use the niobium oxide particles as the microparticles 5 .

Abstract

Disclosed is a multilayer optical device which is a composite optical device wherein an optical resin layer is arranged on an optical base such as a glass base. This multilayer optical device is excellent in reliability since the optical resin layer is hardly separated even under high temperature, high humidity conditions. Specifically disclosed is a multilayer optical device comprising an optical base (1) made of an optical material, an intermediate layer (2) arranged on the optical base (1), and an optical resin layer (3) arranged on the intermediate layer (2). This multilayer optical device is characterized in that the optical resin layer (3) is a resin layer made of an organic metal polymer having an -M-O-M- bond (wherein M represents a metal atom), a metal alkoxide having one hydrolyzable group and/or a hydrolysis product thereof, and an organic polymer having an urethane bond and a methacryloxy or acryloxy group. The intermediate layer (2) is a layer wherein fine particles of a metal oxide are dispersed in a matrix resin which is made of a metal alkoxide having a radically polymerizable group and a hydrolyzable group and/or a hydrolysis product thereof.
